Paul Bettany perhaps has the strangest journey of any of the Marvel Studios actors, beginning as just a voice of Tony Stark’s (Robert Downey Jr.) J.A.R.V.I.S. He’ll transition into a full physical hero this summer in Avengers: Age of Ultron as The Vision. Speaking with Radio Times, Bettany had high praise for the upcoming sequel.

“I’ve never been on a bigger set on my entire life than in The Avengers (Age of Ultron),” the actor says. “One [part] seemed to be the corner of a town, with helicopter cameras, and drone cameras flying about. I just haven’t seen anything that big, so it was like being a kid on a film set again…This is the biggest thing Marvel have ever done. It was enormous. I remember, we were at Comic-con, and they showed a portion of the footage, and I was just gobsmacked. And I looked down the row and every one of the Avengers was the same. Including Samuel Jackson – and his whole modus operandi is ‘I’ve seen everything before, I’m the most chilled out, relaxed man and I’ve seen everything…’and he was as knocked out as anyone. It’s huge.”
